Protestors stand at a makeshift barricade during clashes at a May Day demonstration on May 1, 2013 in Istanbul. Turkish riot police used water cannon and tear gas on Wednesday in a bid to disperse hundreds of protesters who defied a Labour Day ban on demonstrations in a central part of Istanbul. The ban was imposed to avoid trouble during renovation work taking place at the symbolic Taksim square, a traditional rallying point.
